GLUING-MACHINE.

SPECIFICATION forming part of Letters 'Patent No. 267,932, dated November 21, 18(

Application led June 22, 1882.

To all whom it may concern Be it Vknown that I, WILLIAM RABBE, a citi-Y zen of the United States, and a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Gluing-Machines, of which thefollowing is a specification.

My invention relates to an improved gluingmacliine which is especially adapted to lay or 1o evenly spread a coating of glue upon one surface of lumber-such as veneering-strips or boards. It is obvious that leather, paper, and other materials maybe treated in asimilar manner in4 my improved machine.

In the accompanying drawings, Figure l is a central longitudinal section of my improvement. Fig. 2 is a top plan View of the machine.

A represents the legs for supporting the main frame of the machine.

B B represent the table upon which the machine is supported while it is being acted upon by the gluing devices.

C represents the reservoir for holding the melted glue.

D 'represents a drum,which is mounted upon a shaft, D,journaled in the frame A of the machine.

E represents the outer surface of the drum, which is shown as being wound with coarse twine or rope. rlhe coarse twine or ropeV E forms a soft textile covering for the drum, in order to readily take up the glue in the reser- Vvoir, and it is wound spirally thereon, so that the glue taken up by the same will be uniformlyandeectuallyspread uponand throughout the entire surface of the sheet of material to be glued. n..

G represents abrush, secured to the frame A a short distance in the rear of the roller or drum D. This brush is arranged in a planel parallel with the face of the drumD, and located so that the bristles will press against the under surface ofthe material F after it has been acted on by the roller D. rlhe vobject of this brush is to secure a uniform coat of glue applied by the roller D. It may be arranged to be adjusted to or from the surface of the material F, so as to apply the requisite amount of pressure to remove any superabundance of coating, iu case any is applied to the material by the roller D.

(No model.)

If desired, the reservoir C may be made of metal, and an exterior kettle or pan of similar shape adapted to'hold water may surround the reservoir, to which heat can be applied for melting the glue.

I represents a reservoir, which may be employed to hold melted glue, if desired, representing a gate by which glue is fed into reservoir C.

J represents a driving-pulley, mounted on the shaft J', which is journaled on the frame A of the machine.

K represents a transmittinggear, which is mounted upon the shaft J' and meshes with the pinion L, which is keyed upon the shaft M.

N represents a feeding-roll, rigidly attached to the shaft M. Roller N and its shaft M are made adjustable vertically by means of the standard O, which is slotted to receive sliding journal-boxes which are attached to a screw, P, and regulated by a thumb-nut, p, so that the surface of the roller N may be adjusted to or from` the surface of the table B to correspond with the thickness of the material to be glued.

Q represents a friction-roller, the periphery of which engages with the under face of the material F, to assist in carrying it forward over the gluing-drum.

R represents a pressure-roller, located vertically in an axial plane over the roller D. Its oflice is to hold the material E in contact with the roller D. It should be made adjustable,

so as to accommodate the machine to different thicknesses of material. Y

I do not wish to confine myself to the exact form of feeding devices used for propelling the material over the gluing-roller, as other equivalent well-known forms of feeding devices may be employed.

I claiml. In a gluing-machine, the combination of a glue-reservoir, C, supported by a table or frame, and a glue-transferring drum, D, havin g its exterior surface wound spirally with a texl tile material for uniformly spreading the glue on the material to be glued, substantially as described.

2. In a gluing-machine, the combination of a glue-reservoir, C, supported by a table or frame, anda glue-transferring drum, D, having its exterior surface composed of twine or rope IOO 'a planeparallel to the face of the drum to press against the moving material which has been glued, substantially as described.

In testimony whereof Ihave hereun to set my 1 5 hand in the presence of two subscribing Witwound in a spiral direction for uniformly spreading the glue on the material to be glued, substantially as described.

3. 1u a gluing-machine, the combination of a table or frame, a glue-reservoir, C, supported thereby, feed-rollers for carrying the material nesses.
